Telegram is a messaging app with a focus on speed and security, it’s super fast, simple and free. You can use Telegram on all your devices at the same time — your messages sync seamlessly across any of your phones, tablets or computers.

If that's true, Telegram should at least state explicitly what's the limit, that is, how much exactly is considered "abusive", so that all users can avoid reaching that limit and being flagged. In their FAQ it doesn't say anything about that.

I'm interested in this. Is there a document that details how file sharing works in Telegram? Is there a peer-to-peer transfer? Is data cached for some amount of specified time on Telegram servers? How can so much data be stored at no cost to the end users?

Telegram has infinite storage as long as the files are 1,5GB or less. It is perfect for sharing files on channels. It is even better to share files to people because you can just forward the file to whoever you want.

I think there are other platforms but Telegram with its infinite storage and easy sharing takes the cake for me (if you use a PC with it of course).

Storage in Mega is (allegedly) encrypted with keys held only by the user. They can only see and delete content if the user has chosen to share it. Telegram doesn't have this sort of protection (except in secret chats) but so far they also have removed only content in public groups and channels, not in regular chats or personal storage. Or have they?

The don't remove content from private groups or private channels if it hasn't been reported. I don't know how their report system works but it is supposed to be that way.

I still think that comparing MEGA and Telegram is tricky because channels are not really like folders to share. I think we can measure on how much storage we have and how can we share it. MEGA is miles better at speeds and bandwidth. MEGA is a proper cloud storage solution, Telegram just happens to have that cloud storage options as a messaging platform.

I agree comparison with Mega is not quite right. They're not a messaging service after all, and Telegram is. But even tough it advertises itself as a messaging service backed by a cloud infrastructure, and offers peer-to-peer messages, in practice it's more like a free, unlimited private cloud with a messenger on top. It's much slower than other services, but hey, we are getting it for free. And it's super practical for quickly saving files and writing down messages that you have to access in any of your devices later.

I think that Telegram LLC's major flaw is transparency. open source client-side code only won't do. Communication in Telegram is mostly cloud based, and they don't reveal code or implementation details about software running it. It's no wonder there's so much skepticism about a free, unlimited cloud that is a black box. Everybody knows security by obscurity is no true security, they should disclose what software used server side.

I'm not suggesting other messengers are much better or that Pavlov is fooling us. So far, there's no news of Telegram private content being compromised (without user side fuckups, like not using 2 steps verification). But it's kinda hard to defend Telegram on security matters while they keep server-side software a mistery.
